Delete Yahoo (and all its surveilling ilk)

"There are obviously still a lot of questions here including some extremely basic ones. Did Yahoo really do this? Was the request made by the NSA or the FBI? What were the specific terms the company was 'directed' to scan for? What other companies received similar requests and how did they respond? Not to mention the larger questions like what the hell is a security directive? How does it differ from a warrant or a subpoena? Why was it used instead of a subpoena when this was apparently part of a criminal investigation? What gives some random federal agency the authority to issue one? And what law or principle requires any private company to submit to a non-warrant/non-subpoena piece of paper from the fedgov?" (10/05/16)
